Portland cement clinker

Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a .

Cement Production Process | Regain Materials

Clinker and cement production is an intensive process in terms of natural raw material and energy input. Limestone (primary source of calcium carbonate CaCO 3) and clay (primary source of silica SiO 2, alumina Al 2 O 3 and iron oxide Fe 2 O 3) are typically mined in company-owned quarries and pre-blended to a target chemical material composition.

Clinker burning in the cement process of the .

It is the stage in which most of the operating costs in cement manufacturing appear and is also where most opportunities for process improvement exist. The main challenges at this stage in the clinker production are preventing blockages in the preheater, measuring the process accurately and maximizing production in this hot and rough environment.

Manufacturing Process – Continental Cement

The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.
